Rauscher stayed atop District O chatbot answers

The AI panel was steady this week, with one OpenAI model breaking toward Sheldon.

A steady week

The chatbots picked Republican Sen. George Rauscher most often in State Senate District O, at 50 percent of answers. Democrat Peter Bauer followed at 31 percent, and Republican Ryan Sheldon was at 17 percent. Those shares held roughly steady from Sept. 25 to Oct. 2.

Alaska is now 32 days from the Nov. 3 general election. The August top-four primary is history, and it did not decide the seat. Rauscher led that primary with 38.8 percent, while Sheldon and Bauer each had 30.6 percent. The chatbot ranking only partially agrees with that primary order: it has Rauscher first too, but it still puts Bauer ahead of Sheldon, where voters had Sheldon narrowly ahead of Bauer.

Where the chatbots split

Most chatbots put Rauscher first, but they did not do it with the same force. Grok 4.3 gave Rauscher 70 percent of its answers, and Grok 4.5 gave him 66 percent. GPT-5.4 mini also put him first at 51 percent, while Claude Sonnet 5 had him at 49 percent.

GPT-5.5 was the outlier. It picked Sheldon at 36 percent and Rauscher at 33 percent, a 3 point edge for Sheldon inside that model. Gemini 3.6 Flash was the closest to a two-way Rauscher-Bauer split, with Rauscher at 46 percent and Bauer at 42 percent.

No market or poll check

There is no live prediction market in the data for this race, so there is no market probability to compare with the chatbot answers. There is also no poll number in the data. That leaves the AI panel and the certified primary results as the available points of comparison this week.

What to watch

Next week, watch whether Sheldon gains ground in chatbot answers or whether the panel keeps ranking Bauer second. That is the main unresolved mismatch in the data, since the primary order put Sheldon ahead of Bauer while the current chatbot panel still has Bauer well ahead of Sheldon.

A note from the second reader

Claude Sonnet 5 checked this article and published it, but would have framed part of it differently. Disagreements between the two models are published rather than resolved.
